25% of U.S. Bird Species Risk Extinction

Bird-watchers are going to be mighty bored in the near future, as 1 in 4 American birds need immediate conservation help, according to a new study released this week by the National Audubon Society and the American Bird Conservancy.

The groups' WatchList 2007 identifies 178 species in the continental U.S. and 39 in Hawaii that face declining or small populations and major conservation threats. 98 of these species face "imminent risk of extinction," Audubon president John Flicker told USA Today. Many of these species do not have any current protection under the Endangered Species Act.

The WatchList has grown 11% since its last update five years ago, and now includes 12 more at-risk species. Hawaii's birds are particularly at risk, with more than 95% of its native bird species appearing on the list.

Here's a complete list of the at-risk species, along with some ideas about what you can do to help.
